Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run but not cool because of restricted airflow (dirty filter or blocked vents), a clogged coil, thermostat missettings, duct issues, or low refrigerant. A professional diagnostic prevents repeat breakdowns and protects manufacturer warranties. In Marion and nearby Gas City, we offer emergency AC repair, free estimates, and precision tune-ups with a No Breakdown Guarantee.

Quick checks:

• Set thermostat to Cool and lower the setpoint.
• Replace the air filter.
• Clear debris 2–3 ft around the outdoor unit.
• Open supply/return vents.
• If icing is present, turn system Off and Fan On, then call.
